"You're a good looking boy but you're about as dumb as a sack of rocks, aren't you Mickey? You knew your Grandpa was out of town this week, what did you think? Did you think I invited my teenage Grandson to stay with me so we could play board games and share milk and cookies? Look at the way I'm dressed. Have you ever seen tits like these on any of those High School girls you play around with? That bulge growing in your pants is telling me you've finally figured this out. Strip out of those clothes and let me see what we're working with here. Oh yes, that will do nicely. Now come over here and sit on the couch. It's been a long time since I sucked off a High School boy. I was pretty good at it, back in my day, I got lots of practice. As soon as I finish you we'll go upstairs and really get this party started."
